PURPOSE:To enable to obtain a photoelectric conversion element simply and in a short time by a method wherein a polymerizable monomer is performed an electrolytic oxidation polymerization under the existence of a visible light sensitizing catalyst having a negative charge, a conductive high molecular film is formed on an electrode by the monomer, and at the same time, the visisble light sensitizing catalyst is trapped by this film. CONSTITUTION:The monomer is one which forms a conductive high molecular polymer film having a positive charge on an electrode by being performed an electrolytic oxidation polymerization in a solution and has a higher oxidation potential than that of the conductive high molecular polymer. So long as the visible light sensitizing catalyst is one which has a negative charge and can be dissolved in a solvent to be used for performing an electrolytic oxidation polymerization on the monomer, any restriction is not specially imposed to the kind of the visible light sensitizing catalyst. Various ones can be used. However, it is better to use an anion group having a large dissociation degree like a sulfonic acid group as the visible light sensitizing catalyst in order to enhance the trapping property that the visible light sensitizing catalyst is trapped by the conductive high molecular polymer film. The anode used at the time of polymerization is used intact as a working electrode 1 and a conductive high molecular polymer film 2, which has trapped the visible light sensitizing catalyst, has been laminated on the working electrode. |
